Synchronous digital terrestrial interface for TDMA system
Abstract
A digital TDMA interface with the combined features of complete compatibility with an analog interface and no requirement that the earth-based network be modified is described. The article offers a compact description of the earth link, including bit frame structure, the basic design of the digital/analog interface, design realization of the Doppler buffer storage, and compensation for variations in earth-satellite distance. Sixty channels are provided for the TDMA interface module and DSI (digital speech interpolation) module.
